摘　　要：开关控制器是智能化开关设备与二次保护、测控设备接口的必要环节,为适应智能化变电站对开关的智能化需要,笔者提出了一种基于CAN总线和ARM核的智能化开关控制器的实现方案。给出了ARM微控制器和CAN控制器之间相连的硬件电路,论述了硬件接口之间数据通信的实现方法,给出了数据通信的软件设计流程。该方案具备了软、硬件基础,工程应用证明该控制器性能良好。Switch controller is a necessary part in the connection port of intelligent switch device with secondary protected equipment and measure/control equipment. An implementation scheme of intelligent switch controller based on CAN bus and ARM kernel is proposed in this paper to meet the need for intelligent switch in intelligent transformer substation. The hardware circuit between ARM microcontroller and CAN controller is given, the way to implementing data communication among hardware ports is described, and the design cycle of the software for data communication is presented. Engineering application verifies the proposed intelligent switch controller.
